YouTube user jeremytodd1 shares that older xBox 360s can output their display to two televisions without a splitter by utilizing both the composite and component cables—both outputs will be standard definition instead of HD but should suffice for amateur game captures or occasional gaming parties.

Original xBox 360s came with a shared cable that works as both a composite cable and a component cable but is not designed to be used for both simultaneously but it does work if you set the switch on the adapter to TV instead of HDTV. Obviously this won't work on newer HDMI-only xBox models so in that case you'll have to pony up for a HDMI splitter.
